Summary
Different inhaler devices for acute asthma attacks showed similar efficacy but varied costs and side effects. Homemade spacers were cheaper but caused more side effects, while nebulizers were more expensive.
Area of Science:
- Pharmacology and Therapeutics
- Respiratory Medicine
Context:
- Acute asthma attacks require effective and cost-efficient treatment.
- Inhaler devices play a crucial role in delivering asthma medications.
Purpose:
- To compare the efficacy, side effects, and treatment costs of salbutamol administration via nebulizer, metered-dose inhaler with a commercial spacer, homemade spacer, and dry powder inhaler.
- To evaluate clinical scores, lung function (forced expiratory volume in one second), and adverse events in children with acute asthma.
Summary:
- A randomized, double-blind study in 40 children found no significant differences in clinical scores or lung function improvements among the tested inhaler devices.
- Nebulizers and homemade spacers were associated with more side effects (tremor, tachycardia) and higher costs, while commercially available spacers were safer but expensive.
- Dry powder inhalers were cheaper but also caused tachycardia, similar to homemade spacers.
Impact:
- Findings suggest that while efficacy is comparable, device selection impacts treatment cost and patient safety.
- This research informs clinical decisions regarding the most appropriate and cost-effective inhaler device for managing acute pediatric asthma exacerbations.
- Highlights the trade-offs between cost, safety, and convenience in choosing asthma inhaler devices.
